Ammunition-reloading press with angularly adjustable slide

ABSTRACT

A casing-holder slide is slidably mounted on a cylindrical pedestal below a tool-holder head, with its angular position adjustably aligned with the tool axis by means of an eccentric key on the tip of an adjustment shank rotatably mounted in the slide and projecting into a vertical keyway in the pedestal.

3 ZYLE 5. Copcoemv AMMUNITION-RELOADING PRESS WITH ANGULARLY ADJUSTABLE SLIDE BACKGROUND OF THE INVENTION An ammunition-reloading press embodying a cylindrical pedestal rising from a base, supporting a tool-mounting head at its upper end and having a shotgun shell or rifle cartridge holder slide including a collar slidable vertically on the pedestal in response to actuator mechanism, is old and widely used in the art. Examples of such apress, some of simple form and others having a turret-type head for holding a plurality of reloading tools for successive operation of a casing carried by the slide and successively moved upwardly against the successive tools, are shown in the following patents heretofore issued to me:

US. Pat. Nos. 2,772,629, Dec. 4, 1962; 2,819,644, Jan. 14, I958; 3,054,322, .Iune I5, 1959.

SUMMARY OF THE INVENTION This invention is applicableto all such presses. It provides an adjustment shank which extends radially through the slide collar and is rotatably mounted therein by suitable means adapted to hold it against radial displacement and to be simply and readily locked in position. Preferably, such mounting means consists of a threaded connection with the collar and a locknut. At its inner end, the shank has a pivotally mounted eccentric pin carrying a key projecting into a keyway extending longitudinally in the side of the pedestal.

DESCRIPTION The object of the invention is to provide an extremely simple, yet fully dependable means for angularly adjusting the slide with reference to the tool-mounting head of a reloading press, so as to achieve alignment of the axis of a casing held by the slide with the axis of a tool mounted in the head.

This and other objects of the invention will become apparent in the following specification, and appended drawings, wherein:

FIG. 1 is a side elevational view of a reloading press of a simple type, embodying the invention;

FIG. 2 is a horizontal sectional view taken through the pedestal thereof partially above and partially through the slide and below the head;

FIG. 3 is a fragmentary detail vertical-sectional view of the adjustment mechanism, taken on line 33 of FIG. 2; and

FIG. 4 is an end view of the adjustment element, viewed as indicated by line 4-4 of FIG. 3, the pedestal keyway being indicated in phantom.

Referring now to the drawing in detail, I have shown therein, as an example of one form in which the invention may be embodied, a reloading press of a simple type embodying a pedestal P mounted in a base B and having a head H of a type adapted to mount a single tool at a time, fixedly attached to its upper end. A casing-holder slide S is vertically slidable on pedestal P in response to movement imparted to it by a conventional actuator mechanism indicated generally at A. An adjustment key unit K provides a slidable antirotational connection between slide S and pedestal P.

Pedestal P is cylindrical, and may consist of a length of tubing with smoothly finished external surface, its lower end received and secured in a bore (not shown) in base B. Pedestal P has a keyway 9 in the form of an external groove extending vertically in its side parallel to its axis.

Head H may include a cap portion 10 cupped over the upper end of pedestal P and secured thereto,.and a horizontally projecting arm 11 having a tool-holding socket 12 therein.

Slide S includes a cylindrical collar 15 slidable receiving the pedestal P and a horizontally projecting step 16 having a suitable socket 17 to position and hold a shotgun shell or cartridge casin Collar 15 is rotatable on pedestal P to the extent determine by the adjustment of key umt K, and hence they are not shown in detail, being well known in the art.

Key unit K comprises an adjustment shank 20 in the form of a threaded stud which is threaded into an internally threaded bore extending radially through collar 15, and a T-shaped key having a cylindrical stem 21 pivotally mounted in a radial bore in shank 20, and an integral key bar 22 slidable vertically in keyway 9. The outer end of shank 20 projects beyond the collar l5 and is provided with suitable means such as a screwdriver slot or equivalent, for transmitting rotation to the shank. A locknut 23 is threaded thereon, to lock the shank in any selected position of rotational adjustment.

The threads on shank 20 and in bore 21 are of sufficiently low pitch to permit rotation of the shank through an arc of without bottoming the key 22 in keyway 9 or withdrawing it from the keyway to any undesirable extent.

Key stem 21 is positioned eccentrically with reference to the axis of shank 20. In a neutral position the key and shank axis both lie in the vertical plane of the center of keyway 9. From this neutral position the key will be shifted to one side or the other of the vertical plane of the shank axis. Since the pedestal P is stationary, this will result in shifting the shank to one side or the other of the medial plane of the keyway 9, as indicated in phantom in FIG. 4 at 20A and 203. The resultant lateral movement of the shank 20 relative to keyway 9 will be transmitted to the' collar 15, thus causing the collar to be rotatably adjusted around the pedestal P. Correspondingly, the casing-holder step 16 will be shifted transversely with reference to the axis of the tool-holder socket 12 of head II, when necessary, to bring the axis of the casing-holding socket of step 16 into alignment with the axis of the tool-holder socket.

I claim:

I. In an ammunition reloading press, in combination:

a cylindrical pedestal having in its side an external keyway parallel to its axis;

a head carried by the upper end of said pedestal, said head including a laterally projecting part having a holding socket;

a slide including a collar slidably and rotatably receiving said pedestal and a laterally projecting part having a holding socket in axially opposed relation to said head socket;

an adjustment element rotatably mounted in said collar on an axis disposed radially thereof, said element projecting through said collar and being engageable externally thereof for rotatable adjustment;

and a key carried'by the inner end of said adjustment element in an eccentric position and projecting into said y y;

rotation of said adjustment element resulting in lateral displacement thereof with reference to said keyway, such lateral displacement being transmitted to said collar to effect rotational adjustment of the collar around said pedestal.

2. A press as defined in claim 1, wherein said key is of T- form including a cylindrical stem pivotally mounted in the inner end of said adjustment element and an integral key bar slidable in said keyway.

3. A press as defined in claim 1, including a male thread on said adjustment element threaded into a female thread in a bore in said collar, to provide a rotatable connection and to hold said element against displacement along its own axis.

4. A press as defined in claim 3, including a locknut on a projecting outer end of said adjustment element, to lock it in its adjusted position. 

1. In an ammunition reloading press, in combination: a cylindrical pedestal having in its side an external keyway parallel to its axis; a head carried by the upper end of said pedestal, said head including a laterally projecting part having a holding socket; a slide including a collar slidably and rotatably receiving said pedestal and a laterally projecting part having a holding socket in axially opposed relation to said head socket; an adjustment element rotatably mounted in said collar on an axis disposed radially thereof, said element projecting through said collar and being engageable externally thereof for rotatable adjustment; and a key carried by the inner end of said adjustment element in an eccentric position and projecting into said keyway; rotation of said adjustment element resulting in lateral displacement thereof with reference to said keyway, such lateral displacement being transmitted to said collar to effect rotational adjustment of the collar around said pedestal.
